In 2050, on a sunny summer morning, Anna walks along the banks of the Danube in Budapest. The streets are quiet, the air is crystal clear. The green energy revolution, which began in 2025, has completely transformed Europe. Wind and solar power drive cities, fossil fuels have been completely replaced by sustainable solutions.

Cars run silently through the streets – all self-driving and electric. Transportation is so advanced that urban traffic has almost disappeared. Anna goes to her favorite breakfast room, where dishes are made with local ingredients using a 3D printer.

Over the past 25 years, education has also changed: Online and practical learning are in perfect balance. Anna's children are learning to understand a world in which the cooperation of technology and nature is fundamental.
